Personalized cochlear implant programming guided by human inner-ear anatomy
Improving Cochlear Implant Outcomes Through Modeling and Programming Strategies Based on Human Inner Ear Pathology
This project builds 3-D maps of donated human inner ears to help create smarter cochlear implant settings for children and adults so they can hear speech more clearly, especially in noisy places.

What this research studies
As someone with a cochlear implant, this work looks at donated human inner-ear tissue to understand how electrode position and nerve health affect hearing. Researchers will apply machine learning to generate detailed 3-D reconstructions showing electrodes relative to surviving auditory neurons. They will use those reconstructions to create computational models and clinical measures that predict better implant programming for individual listeners. The findings are intended to guide programming strategies that can later be tested with cochlear implant users.
Who could benefit from this research
Good fit: Adults and children who have cochlear implants or are candidates for implantation would be the primary people who could benefit from clinical tools developed here.
Not a fit: People with hearing loss who do not use cochlear implants or whose hearing cannot be helped by programming changes may not receive direct benefit.
Why it matters
Potential benefit: If successful, this could enable more personalized implant settings that improve speech understanding, particularly in noisy environments.
How similar studies have performed: Previous modeling and programming approaches have shown promise, but using detailed 3-D reconstructions from human temporal bones with machine learning is relatively new and not yet proven in patients.
